When applying image to product files, it is important to make sure that you are providing a direct URL to a single image using the image columns on the product upload template.The URLs must point to an image(s) that are publicly accessible and can be accessed from any computer or device. It is important that your image URLs need to point to the image itself (and not to a preview html page with the image embedded in the markup).
